According to the Aftonbladet newspaper, Munir Awad had shared a flat Stockholm with two men who were convicted in December in Gothenburg. The district court sentenced the two men, Elias Billé Mohamed, 26, and Mohamoud Jama, 23, to four years in prison after finding that they were preapred to commit suicide bombings in the name al-Shabaab, a Somalia-based Islamic militia with ties to al-Qaeda.

Meanwhile, a 26 year old Iraqi asylum seeker who was also arrested in Denmark but has since released has claimed his innocence.

“I am completely clean” he told the Danish newspaper Ekstra Bladet.

The 26 year old maintains that he thought his apartment would be lent to a Swedish man and his wife, but when he went to meet them outside Tivoli Gardens in Copenhagen, there were three men there instead.

Four men were arrested on Thursday in a joint Swedish-Danish investigation for hatching what Danish officials called a plan to “kill as many people as possible” in an imminent assault on the Copenhagen offices of the Jyllands-Posten daily.

In 2005, Jyllands-Posten published a dozen cartoons of the Prophet Muhammad that triggered violent and sometimes deadly protests around the world.

On Wednesday Jakob Scharf, the head of Danish intelligence agency PET, told reporters “the plan was to try to gain access to the location of Jyllands-Posten in Copenhagen and to try to carry out a Mumbai-style attack.”
